An outer surface of the bead portion TB includes a seat surface 24, a flange surface 26, and a heel surface 28. An inner diameter dw of the core 18, a rim diameter D, an inner diameter dA of the tire 2 at a heel reference point PH, and an inner diameter dB of the tire 2 at the seat reference point PS satisfy the following formulas. dw/D≥1.0041dA/D≤0.9966dA−1.72≤dB≤dA−0.73
